THREAD-CUTTER.

Specification of Letters Patent.

Application filed September 5, 1919. Serial No. 321,786.

To all whom it may concern.

Be it known that we, LEWIS G. Fnrrz and Amt-no A. I-Innznnnenn, citizens of the United States, and residents of MeCutchenville, in the county of Wyandot and State of Ohio, and Indianapolis, in the county of Marion and State of Indiana, respectively, have invented certain new and useful I1n-' provements in Thread-Cutters, of which the following is a specification.

Our invention is an improvement in thread cutters, and has for its object to provide a device of the character specified, preferably mounted upon a finger ring and having means for cutting the thread, cord or the like, so held that there, is no possibility of injury to the wearer, and having means for guiding the thread into the cutter.

In the drawings:

Figure 1 is a perspective view of the improved cutter;

Fig. 2 is a side view showing the cutter and a portion of the ring;

Fig. 3 is a front View;

Fig. (l is a view similar to Fig. 1, showing a modified construction;

Fig. 5 is a vertical section cutter.

In the embodiment of the invention shown in Figs. 1 to 3, inclusive, the cutter is in the form of a blade 1 which is held in a substantially U-shaped sheath 2, the side walls of the sheath being cut away near one end, as indicated at 3, to expose the cutting edge of the blade at this point and a portion of-the blade .itself.

The cutter is preferably mounted upon a ring of suitable material and size, the said ring being a split ring as shown. At one of its ends the ring has an up-turned through the lug 5 and. this lug maybe continuous with the sheath, or it maybe soldered thereto as may be desired. In the present instance the lug, that is, the ring,'is integral with the sheath. The ring has a struck up lug 6 adjacent to the cut away portions 3 of the sheath, and this lug is split to receive the blade. The lug inclines upwardly and outwardly, fitting against the rear end of the cut away portions 3 and the said lug acts as a guide to guide the thread or cord to the cutter.

In the embodiment of the invention shown In Figs. 4 and 5 the blade 7 is held in a sheath 8 and the sheath is supported by a split ring 9. The ring has a struck up lug 10 which is split to receive the blade at the cut away portions 11 of the sheath, and the said lug 10 acts to guide the thread or cord to the blade. At each side the sheath is provided with extensions 12 at the rear ends of the cut away portions 11, and these eX tensions pass through an opening 13 in the ring 9. The extensions arethen bent'outwardly and upwardly upon the inner face sheath to the ring.- The sheath in the present instance is integral with one end of the rin although it is obvious that it might be separate therefrom and secured thereto Patented Aug. 3, 1920.

' of the ring, as shown in Fig. 5, to hold the which may be worn upon any finger, insures 1 that it is always at hand when needed and in convenient position to apply.

The device is especially suitable for seamstresses, clerks and the like, and may also be used for cutting cloth instead of scissors. The provision of the split ring permits a degree of adjustment, and it will be understood that all of the parts may be of any suitable or desired material.

We claim:

'A thread cutter comprising a split ring for engaging the finger, one end of the ring having integral therewith an extension bent over upon the outer face of the ring and shaped to form a sheath, a blade held in the sheath, the sheath being cut away on the edge adjacent to the face of the ring and near the end remote from the connection with the ring to expose the cutting edge of the blade, and a support for the sheath at the cut away portion, said support having an inclined surface for guiding the thread to be cut toward the blade.
